nRF Sniffer on nRF52840 Version 3 installation error

Yes. If you select the peripheral while it is advertising from the dropdown menu:

It will follow that device into connection. If you are using pairing or bonding with Out of Band keys, you can also enter the key in the Passkey/OOB field (right next to the dropdown menu), and it will be able to decrypt the encrypted messages as well.

BR,

Edvin

Thanks Edwin.

I have the nRF sniffer working, but all I see are advertising packets.

Is it possible to have the sniffer follow connection requests it captures?
If so how do I enable this.

[quote user="cycledude"]Thanks. So the Programmer recognizes that the code is invalid and disables all to install it?[/quote]

Not sure what you mean, but the reason you don't see the dongle in the programmer app is because you programmed it with an application that doesn't use the USB at all, and hence the USB will only be used for power source. If you press the reset button (Not the white button, but the "sideways" button next to it) while the dongle is connected to USB power, it will re-enter bootloader mode, and you can program new applications to it. However, it will still not work with the nRF Sniffer. But now you can at least use it for something else.

Best regards,
Edvin

[quote user="cycledude"]Sorry Edvin, I should have included that I was using Python version 3.7.6[/quote]

No problem :) Thank you!

I was not aware that you were using the dongle. Unfortunately, the dongle isn't supported in the BLE sniffer.

pca100XX is the name of the different HW that we have. pca10056 is the nRF52840 DK, while the pca10059 is the nRF52840 dongle. The reason it doesn't work to use the nRF52840 DK FW on the dongle is because the FW uses UART, via the debugger on board to translate from uart to USB. On the dongle, the UART pins aren't connected to anything, and it doesn't have a debugger to translate from UART to USB.

The USB part on the dongle is the actual USB peripheral on the nRF52840. Although technically possible, we don't have any FW for the nRF Sniffer that does this at this point in time. I am sorry.

Best regards,

Edvin

Hello Rick,

Sorry if I'm bothering you.

I just had a few things that I wanted to finish before reporting this internally since you had it up and running. I wanted to check whether I was able to reproduce the issue that you had with the previous version of Python. If it is, in fact, a bug, we should either update the documentation or find a fix, so that others don't need to struggle with the same.

So which version of Python did you use before you updated to 3.8.1?

Have a nice weekend.

Best regards,

Edvin

Hi Edvin, I am having issues with loading hex data on my nRF52840 dongle.
I was unsure of which hex code to load. I started to load hex files using trial and error to find the correct one.
Unfortunately after loading the first one I am no longer able to erase and & Write as all the device commands are greyed out except the Reset.

Also what is the correct hex code?

Can you please assist?

Rick

Hi Edvin, I used Python 3.8.1.

Thanks again.

Glad to hear that it worked out. What version of python 3.7 did you use? I will report this internally to either fix the bug, or update the description/requirements.

Best regards,

Edvin

Thanks Edvin!!! that worked. I am capturing BLE traffic now.

Thank you for all your assistance, you have enabled me to start developing.

Hello Rick,

Did you copy all of the files and folders from the downloaded extcap folder to the wiresharks extcap folder?

Can you double check that you have the correct python version in the path when you type "python --version"?

If it still doesn't work, can you please try to install python 3.8.x? I have this installed on my computer, and I just installed nRF Sniffer version 3, and I didn't experience any problems. If that works, I will report this as a bug internally (because it says that version 3.5 or later should work).

Best regards,

Edvin
